interactive
     
         A term describing a program whose input and
        output are interleaved, like a conversation, allowing the
        user's input to depend on earlier output from the same run.
     
        The interaction with the user is usually conducted through
        either a text-based interface or a {graphical user interface}.
        Other kinds of interface, e.g. using {speech recognition}
        and/or {speech synthesis}, are also possible.
     
        This is in contrast to {batch} processing where all the input
        is prepared before the program runs and so cannot depend on
        the program's output.
